The bright colors and the prominent display of the 'Courses U' logo and app interface.

The video showcases the 'Courses U' mobile app interface. It starts with a bright blue background and the app logo. The phone screen displays the app's homepage with a search bar, promotions, and various sections like 'My Advantages', 'My Lists', and 'My Orders'. The interface transitions to show product listings with prices and ratings, highlighting 'Prix Mini' (minimum price) items. The final scene shows the app logo again with text about drive or delivery options, and icons for a smartphone and laptop.
